Jack,
I used to visit County Record Offices ( Nbl, Durham, Tyne & Wear, Cleveland) and larger libraries, to dig for the three main sources of info for Fam Hist... Censuses, BMD Registrations and Church records of Bapts, Marriages, Burials... several times a week.
But because of the increasing amount of info on line, I usually only get to "physical" archives to search church records, of which there is not a lot on line..... but growing.
But for Censuses ( 1841-1901) info , I use a commercial web site for ancestry searching.
